Cossack Hetmanate and Sloboda Ukraine
In Ukraine of the 17th and 18th centuries, an osaul was a military and administrative official performing the duties of aide-de-camp.[2] The head of state, hetman, would appoint up to two osauls known as a General Osaul. There also was a Regimental Osaul as well as Company Osaul, with each regular cossack regiment and company except artillery having two of each. Beside them there were osauls under special assignments, one of them serving for General Obozny (quartermaster) who performed duties of a chief executive and was the second in importance after the Hetman.
